The intertwining black and white colors were the visible forms of refined Qi and Magic. Every collision between the two increased the amount of energy that was released. The law of conservation of energy still held true. This type of energy increase was more properly explained by the conversation between mass and energy. Such conversion was much more powerful than the release of energy taken place in a typical hydrogen bomb.
Hydrogen bombs converted less than one percent of its total mass and the resulting explosions enormous. Imagine a conversion that turned a hundred percent of mass into energy. There was a joke that you could bomb the Earth with a chair. A chair that was completely converted into energy would probably have the power to blast the Earth to pieces.
